Diwali is that festival in India on which people buy more of electronics, and no doubt Flipkart is the best online shopping website in case of Electronics mainly. You will get a vide variety and range of electronics there. I have been shopping with Flipkart since 3 years now, and every time I shopped with it I was satisfied. They are genuine with the delivery time too(infact most of the time you get the delivery in 1 or 2 days only). But yes if you want to buy clothes, I suggest don’t go for it.
Happy Shopping with Flipkart!
